A novel data placement scheme on optical discs for near-VOD servers
Recent advances on computing and communication technologies have made it possible to provide digital video services through network. One of the economic and practical applications is near video-on-demand systems. In this paper, a novel data placement scheme on optical discs is proposed for providing near video-on-demand services. By applying the scheme, the seek time of an optical disc drive is almost eliminated, and the bandwidth utilization can be optimized. Then, the maximal number of supported streams from an optical disc drive with the minimal buffer requirement can be easily achieved. The scheme can be applied not only to CDROMs storing MPEG-1, but also to Digital Versatile Disks (DVDs) storing MPEG-2 in the near future.
